set_role_permissions

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full behavioral burden but only discloses that preview and mutation are both possible. It does not explain permissions requirements, reversibility, side effects, default behavior, or what confirm changes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The single sentence is front-loaded and free of filler, so it is efficiently structured. It is very terse for a complex mutation tool, but conciseness itself is not the issue.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 5-parameter, nested-object mutation tool with no annotations and no schema descriptions, the description is far too thin. Although an output schema exists, the agent still lacks essential context about confirm semantics, permission shape, and permlevel behavior.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate for undocumented parameters. It mentions DocType, role, and permissions at a high level, but does not explain confirm, permlevel, or the boolean structure of the permissions object.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb pair ('Preview or set') and resource ('DocType role permissions'), making the tool's purpose clear. It does not explicitly distinguish this tool from nearby siblings such as set_field_property or export_customizations, so it falls short of the top score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It says 'Preview or set' but gives no guidance on when to preview versus when to apply changes, nor how that choice relates to the confirm parameter. No alternatives or exclusions are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
